  through during its life cycle.

• Frogs have a life cycle with two parts, living in
  water as tadpoles and on land as adults.

Tadpole

• The second stage of the frog life cycle is the
  tadpole.
• Hatched tadpoles have gills for breathing in the
  water.
• They have a tail, but no legs.

As a tadpole grows, lungs begin to form.

Froglet

• The next stage of the frog life cycle is the
  froglet.

• These legs help the frog on land.

10
Adult Frog

• Once the lungs form and begin to work, the gills
  and tail disappear.
